The ZoneKnit™ Insulated LS Hoodie by ICEBREAKER for men is a high-performance merino wool baselayer optimized for intense activity and technical mountain pursuits.

The warm yet highly breathable ZoneKnit™ Insulated Long Sleeve Hoodie features ICEBREAKER’s ZoneKnit­™ engineered body mapping, which combines merino jersey fabric with strategic panels of merino eyelet mesh to enhance airflow and temperature regulation.

On the chest of the ZoneKnit™ Insulated Long Sleeve Hoodie by ICEBREAKER a panel of MerinoLoft™ insulation, a natural and cruelty-free merino fill, adds key core warmth where it’s needed most. The balaclava hood increases protection, while underarm gussets and raglan sleeves provide uninhibited range of motion.

Inspired by nature, ICEBREAKER harnesses the performance qualities of natural fibers to offer an alternative to clothing based on petrochemical synthetics. Merino is an annually renewable fiber that naturally resists odors, keeps you cool when it’s hot and warm when it’s not, and lets your skin breathe for comfort all day, every day.
